In computing, part of the magnetic structure created on a disc surface during disc formatting so that data can be stored on it. The disc is first divided into circular tracks and then each circular track is divided into a number of sectors.
One of numerous circular data storage areas on a floppy disk or a hard drive, comparable to a groove on a record but not spiral. Tracks, composed of sectors, are recorded on a disk by an operating system during a disk format operation. On other storage media, such as tape, a track runs parallel to the edge of the medium. See the illustration.
